Embodiment Construction

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] figure 1 Shown is an application scenario of a satellite network based on on-board IP routing switching, wherein the satellite network includes on-board routing switching equipment, satellite terminals and satellite network users, and the on-board routing switching equipment connects adjacent satellites through inter-satellite links It connects satellite terminals under different beams through satellite-ground links. The onboard routing switching equipment and satellite terminals adopt the RIP optimization protocol (hereinafter referred to as the S-RIP protocol) to complete the learning of routing information and the generation of routing and forwarding tables, and realize fast forwarding of satellite user data within beams, between beams and between satellites .

[0028] like figure 2 , 3 As shown, the method includes the f...

Abstract

The invention relates to an RIP protocol optimization method suitable for on-satellite IP routing exchange, and belongs to the technical field of satellite communication. According to the invention, the satellite network RIP routing dynamic rapid learning based on the on-satellite IP routing exchange is realized through the design of interface network configuration information automatic sensing, on-satellite RIP message in-beam forwarding, RIP message format and routing algorithm optimization and the like. The method can be applied to satellite network scenes with on-satellite IP routing exchange and inter-satellite interconnection, and the problems that when a standard RIP routing protocol is applied to a satellite network, cross-satellite and cross-beam routing convergence is slow, and dynamic networking RIP routing learning in a single beam is difficult are solved.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to a RIP protocol optimization method suitable for on-board IP routing exchange, which can be used to realize dynamic and fast learning of satellite network RIP routing based on on-board IP routing exchange, and solve the application of standard RIP routing protocol For satellite networks, there are problems such as slow convergence of cross-satellite and cross-beam routes, and difficulty in learning RIP routes for dynamic networking within a single beam. Background technique [0002] After decades of development, my country's satellite communication system construction has made great progress. Driven by the global seamless coverage and user access requirements, the satellite communication system has begun to develop from the single-satellite transparent networking to the multi-satellite integrated networking. The IP protocol suite and related routing have been intro...
